This game is for adults. Some puzzles are realy difficult, some solutions are unexpected. I spend a lot of time here, though the game is short. Arts are beautiful, background sounds are atmospheric, the story itself is fascinating and enlightering. The is no indulgence for a new player, you will spend much time on first encountered puzzles, but when you understand the logic and get accuanted with mechanics, game becomes a little bit easier. Must have game at least to check is your brains still okay or not.
